A young policewoman's debut at the Major Crimes division in Paris.

2015: recruited to the Major Crimes division, a young policewoman from the provinces finds herself at the prestigious Paris headquarters of 36, quai des Orfèvres. Only 25, she discovers the world of homicides, open cases, seemingly insurmontable responsibilities, prestige, thankless drudgery, competition, big city loneliness—in short, the job. Confronted with unimaginable crimes as well as the banality of evil, surrounded by those she deems the cream of the cop crop, this young recruit is about to do a whole lot of growing up, and fast.
